Chromia (ROTF)
| The name or term "Chromia" refers to more than one character or idea. For a list of other meanings, see Chromia (disambiguation). |
- Chromia is an Autobot from the Revenge of the Fallen franchise in the live-action film continuity family.

Chromia is a tough bot, optics always scanning for the next fight. Naturally that means she and Ironhide agree on a lot of things. This combined with the countless battles they fought together in made for a friendship that has lasted centuries. When the conflict on Earth escalated, both seasoned warriors were pleased to be working together again.
Fiction
IDW live-action film prequel comics

During the dark period of Cybertron's history when the AllSpark was lost and the planet drifted through the cosmos without a sun to orbit, Chromia and her sister Arcee lived in Metrotitan. Once both the previous problems were rectified and Cybertron entered a new era of freedom, their older sister Elita-One was able to be reunited with them. Foundation #1 The three sisters were present when Sentinel Prime announced that Cybertron would be under the dual rule of Optimus Prime's Science Division and Megatron's Defense Force. Chromia chose to join the Defense Force, where she befriended Ironhide and aided in taking out "malcontents" who were opposed to the new order. Foundation #2 Many years later, she and Ironhide witnessed Optimus and his team escape an assassination attempt by Starscream. She followed Optimus to an excavation site and helped him foil an attempt on Sentinel, Elita and Wheeljack's lives.
During the war, Chromia, Ironhide and Arcee led an assault on Simfur Temple, so Elita could use the AllSpark to activate a "torch" created by Sentinel that would end the war. Foundation #3 Megatron knocked Chromia aside, and Ironhide carried her off the battlefield when Sentinel's ship was destroyed. With the Decepticons weakened after the initial attack, Chromia soon returned with Arcee on Wheeljack's Ark and stole the AllSpark. Foundation #4

Around the year 1908, many years after the war broke out, Chromia and Elita-One were part of an Autobot team sent to steal energon from the Decepticons. Instead they were ambushed by Shockwave and his troops, and Chromia was killed in action. Her corpse was taken by the immoral Decepticon scientist Flatline, who considered it perfect for use in his experiments. Rising Storm issue 2
Flatline took Chromia's body (along with the corpse of her sister Elita, who had died later on) to his lab at an outpost on an unknown planet to use in his attempts to create a new breed of tripartate soldier, three bodies fuelled by a single spark. After several failures, whether by coincidence or design, Flatline was presented by Thundercracker with a new test subject: Elita and Chromia's sister, Arcee. Through the use of Arcee's spark, implanted in a new body, Flatline reignited the life-forces of Elita and Chromia in new shells, albeit not as they had truly had been before: now, they were at one with their sister, a singular entity at the spark, each feeling the sensations and emotions of the other, yet retaining some degree of autonomy and memory of their own identity. "One as three, and three as one". Grappling with their new forms, the sisters broke free, liberating Flatline's other victims, the twins Skids and Mudflap, in the process. Tales of the Fallen #6 Rising Storm #1

A short time later, the sisters, the Twins, Sideswipe, Jolt, Topspin, Leadfoot and Roadbuster arrived on Earth on the Wreckers' ship, the Xantium Dark of the MoonDark of the Moon issue 3 in response to a summons beamed into space by Optimus Prime. Joining the allied Autobot-human strikeforce NEST, the new recruits received some training, and were soon called upon to put it into use: the Decepticon Demolishor had been sighted in Shanghai, China. Alliance #4
Revenge of the Fallen film
- Voice actor: Grey DeLisle (English), Masako Katsuki (Japanese), Martina Treger (German), Chiara Colizzi (Italian), Gabriela Bicalho (Brazil)
- Holographic rider: Erin Naas
Chromia and her sisters were held in reserve as NEST entered Shanghai to deal with Demolishor, only being called into action when the presence of a second Decepticon, Sideways, was detected. Together with the twins, the sisters pursued the sneaky speedster through the streets of Shanghai, smashing through buildings and everything else in their way, but they were ultimately unable to do little damage, so Sideswipe was brought up to bat, and proceeded to make short work of Sideways.
When The Fallen issued an ultimatum to Earth, the US government decided that the Autobots would be shipped back to Diego Garcia, but NEST disobeyed the orders, instead shipping Elita and the others to Egypt on the advice of Sam Witwicky, who had the means to resurrect the recently-deceased Optimus Prime. During the climactic battle between NEST and The Fallen's Decepticons, the sisters arrived with Ironhide to help escort Sam and Mikaela through the warzone, but both of Chromia's sisters soon fell to Decepticon firepower as the conflict heated up.

Toys
Revenge of the Fallen
Deluxe Class toys

- Chromia (Deluxe, 2009)
- Japanese ID number: RA-11
- Accessories: Missile, figure stand/cycle cannons
- Chromia converts from a Suzuki B-King to... a unicycle. Her vehicle mode weapon can attach as a display stand for either mode, ironically making a unicyclebot one of the most stable robot-modes. In robot mode, there is a spring-loaded missile between the tailpipes on Chromia's left hand in addition to the aforementioned non-firing blaster-stand. There is also a piece on the bottom of the vehicle mode (or back of the robot mode) that folds out, but there is no indication in the instructions as to what this piece is for. It appears to be part of an unmentioned combiner gimmick for the Arcee triplets, as it locks together with a similar piece on Arcee, with room for a third robot to connect.
- While the instructions depict the motorcycle seat remaining flat so that it ends up covering the bottom wheel, the robot mode more closely resembles the movie design if the seat is folded in and locked into a slot on the motorcycle's bottom, as shown on the back of the packaging. The packaging photo also shows Chromia's front wheel resting behind the robot's shoulders, while the instructions leave it above her head. Furthermore, while it is not mentioned either in the instructions or shown on the box, the stand can be attached backwards and rotated with the guns facing up so that it acts as a prop for the toy, allowing the wheel to actually touch the ground, and letting the toy look from the front like it is unsupported. In addition, the stand can also be attached to right arm as an inordinately large handgun by sliding the two pegs inside the gun into two slots on the inside of the arm.
- The stand has sculpted tank treads on the bottom, most likely to make it look that she's still mobile while using it.
- Though the instructions do not explain it, the back of the blister card mentions she has a Mech Alive gimmick in her left arm. While it isn't quite the "spinning gears" the card refers to, swinging her left forearm towards and away from her body makes a blue piston slide back and forth inside the large gun. An aborted light-piping gimmick that uses clear plastic instead of the more usual blue is also present, however it is rendered useless by opaque paint applications to her optics.
- This mold was also used to make Transformers (2010) Elita-1 and Dark of the Moon Arcee.
Human Alliance

- Mudflap / Chromia / Seymour Simmons (Human Alliance, 2010)
- Japanese ID number: RA-31
- Human Alliance Chromia comes with Mudflap and Seymour Simmons, and is designed so that Simmons can ride her vehicle mode. Despite the coloring and name, the toy actually uses Arcee's design rather than Chromia's. She has a kickstand in bike mode, though it's too short to hold her completely upright.
Transformers (2010)

- Sideways Sneak Attack (Multi-pack)
- This Target exclusive multi-pack was to contain redecos of the Revenge of the Fallen Legends class Arcee mold as Chromia and Elita-1, plus an Arcee who may or may not be different from the single ROTF release. The set furthermore includes a redeco of Deluxe class Sideways, whose painted battle damage evokes the scene in the film where he's been cut in half. Ouchies.
Merchandise
Revenge of the Fallen

- Chromia vs Megatron (2009)
- Part of the third wave of Robot Heroes two-packs for Revenge of the Fallen, Chromia comes packaged versus Megatron. Her robot mode design is actually Elita-1's, since Hasbro can't tell their bike chicks apart.
Notes

- Whether or not Chromia is a unique individual or just an extension of Arcee is a matter of debate.
- The three bike girls were originally going to combine into a larger robot-form, but this was cut from the final movie. At Botcon 2009, Hasbro reported that the toys are still capable of this combination, but that it will not be mentioned in the instructions for the figures.
- The Arcee toy that comes with Human Alliance Skids and Mikaela has Chromia's robot design but transforms into Arcee's bike mode, while the Chromia toy that comes with Human Alliance Mudflap and Simmons has Arcee's robot mode but transforms into Chromia's bike mode.
- Meanwhile, Chromia's Robot Heroes figure is actually Elita-1's design. Man, what is going on, peeps?
- In pre-production artwork, the non-pink components of the proposed combined Arcee were variously shown to be gold, green or silver. Which portions of these monstrosities may have originally been Chromia is anyone's guess, but the inclusion of a blue bike amongst the group was apparently decided upon by the time the film's animatics were created.
- Chromia is the only suviving Arcee sister, as shown in Dark of the Moon.
